反応手順

A mixture of N,N-dioctadecylcarbamyl chloride (2.9 g.), N,N-bis-(2-hydroxyethyl)-1,2-ethanediamine (4.0 g.) and benzene (50 ml.) is refluxed and stirred for three hours. The mixture is then cooled, concentrated in vacuo and the residue taken up on chloroform (100 ml.). The chloroform solution is washed successively with water (2 × 50 ml.), aqueous sodium hydroxide (1 × 50 ml. of 1N) and water (2 × 50 ml.), then dried (Na2SO4). Removal of the chloroform in vacuo leaves the crude product as an oil (3.3 g.).
